Repeating yourself won't help because from my point of view I've answered your question. I showed you how to "wire up the logins again" which would appear to be the source of your other problem. I assume you have sorted out the users on the moved database - What is your problem now?

Are you really that lazy that you cannot type "at"? (It is the only word that fits, but it took me quite a few seconds to figure that out - Do you really expect a prompt reply when it takes people an unnecessary amount time to figure out what you are writing?!

I don't know - that depends on your database.

If the user in the database has db_owner rights then the user will be the owner of the database, and that user must be associated to a login.

shaz jazz wrote:
there is no owner of this database

Find out which user or users are marked as the database owners (they have db_owner rights on the database, or sysadmin rights over the whole server) and apply them on your database at home.

shaz jazz wrote:

I've never seen this error before, So I'm guessing that you have to use the same user as the owner as where the database was created. You need to use ensure that user has a valid login and that user is granted the db_owner rights on your server at home. As it is a lab experiment, you might want to elevate that to sysadmin rights (which will give that user the right to do anything on the server, not just the database).

Wait a moment: Are you moving a SQL Server 2000 database onto a SQL Server 2005 system? If so then the diagrams won't work - It is a known limitation, SQL Server 2005 does not read SQL Server 2000 diagrams and the tools for SQL Server 2005 won't create diagrams on a SQL Server 2000 database.

"

If you restore a db with its security context (It has users). You have to delete them from the db then add then again. If the users don't exist on the SQL box you have to create them.

Convert filtered dataview to datatable

I have a dataview then i use rowfilter on htis dataview.
now i want to convert this filtered dataview to datatable or to dataset.Is there any method or i have to write my own logic.

OK your slightly unclear here.

You can create a new datatable in your current dataset and "copy" the data from the dataview in there.

or

Create a new dataset, create a new datatable in the new dataset and you guessed it "copy" the data from the dataview in there.

DataSets are collecton holders of Tables, Views etc.

ADO.net Connection

Hi Everybody,

I have a problem with the ADO.NET Connection which i use in my coding in VB.net 2005, to connect to the SQL Server 2000.

This connection works properly on a local machine , when i set the servername as localhost. but when i set the servename as the name of the server on which the SQLServer is installed, it doesn't work. whereas the ADO Connection does.(Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=Test;Data Source=" & ServerName)

The ConnectionString I'm using is "Data Source=" & ServerName & ";Initial Catalog=DatabaseName;Integrated Security=true"

Thanks, in advance
Regards,

Myra

Your ADO connection is passing a user id and password. Your ADO.NET connection is using a trusted connection. Could that be the cause of the problem?

This has nothing to do with the connection. This error message can only be generated after .NET has successfully connected to the database. The error message is telling you that the command you sent the SQL Server is taking longer to return the results than the timout allows (by default the timeout is set to 30 seconds).

the connection timeout is equal to 15.

There are two timeouts. Since you are allready connected changing the connection timeout will not help you. The timeout is occurring on the command - it is the length of time that the command is taking to execute. SqlCommand.CommandTimeout is 30 (seconds) by default.

You can, of course, just increase the timeout. Or you can examine the SQL you are sending to the database to try and determine why it is taking too long. However, since you have not given any information on the SQL Command you are sending to the database I cannot help you with that.

I tried to add to the connection string : "Connect Timeout=30", and it worked.

I have two table with one-many relationship
table1 has 2 fields:type(int,PK),name
table2 has 4 fields:id(PK),type(int,FK reference field type of table1),content,shortDesc

How to write a SELECT statement that return rows from table1 join table2(via type field) but each row has a different value of type.
Result example:
--------------------------------------------------
| table1.type | name | content | ShortDesc | <--- FIELDS NAME
--------------------------------------------------
| type1 | name1 | content1| shortDesc1 | <---VALUE( ROW )
--------------------------------------------------
| type2 | name2 content2| shortDesc2|

Can anyone help me.Thanks in advance

Sorry but the statement don't return what i expected
Example:
type1 |Id1 | name1...
type1 |Id2 |name2...
because there's a one-many relationship between 2 table
Thanks anyway

However, it does return what you asked for.

You asked for: | table1.type | name | content | ShortDesc |

The SELECT statement returns: table1.type, table1.name, table2.content, table2.shortDesc
name only exists on table1, content and shortDesc only exist on table2

You are now asking for something with an example output of:
type1 |Id1 | name1...
type1 |Id2 |name2...

This is not possible because name is on table1. Therefore any output row that contains type1 must also contain name1. An output row containing type1 cannot contain name2

ali33 wrote:

Yes, I know that - That is what I gave you. I suspect that either you did not give the full information when you asked the question or you do not understand the implications of the join scenario.

oh!sorry . I have a mistake

When I run your SQL statement the result return is:

type1 |Id1 | name1...
type1 |Id2 |name1... <---(sorry not name2)
But the result I expected is:

type1| Id1 |name1...
type2| id2 |name2...
type3| Id3 |name3....
(each type return only one ID of table 2,for all type)
Sorry for the mistake and can you help me.Thanks

Sorry, but I'm still convinced my SQL is correct.

Show me an example of a few rows from each table that should match and tell me for each row in table1 what rows in table2 match to it.

I see now. You need to aggregate the rows in table2 somehow then join it. However there is no natural aggregation that you can use. From your example result set you appear to be taking the lowest id for each type - so that is the colum that needs to be aggregated.

This is the aggregation component:

SELECT MIN(id) AS id, type
FROM table2
GROUP BY type

It basically takes the first row for each type and discards the rest.

Now it has to be joined up. The result of the aggregation is added to the previous join to act as a filter.

SELECT table1.type, table1.name, table2.content, table2.shortDesc
FROM table1
INNER JOIN table2 ON table1.type = table2.type
INNER JOIN (SELECT MIN(id) AS id, type
            FROM table2
            GROUP BY type) AS filterQuery ON filterQuery.id = table2.id

This should now produce the results that you want.
